Language: English
Cost: No chargeIf an E&P development project is technically – and commercially – mature, future production associated to the project, can be classified as reserves, and Reserves-Based-Lending (RBL) would become an opportunity.

In this webinar we focus on the requirements that need to be fulfilled to move a project from the contingent resources to the reserves category. A project for example, consists of drilling of new wells, as part of a work program or a full field development, underpinned by a sound field development plan. We will provide insight into how the chance of commerciality may be improved, among others. This information could be helpful in a low oil price environment where a company’s reserves base will be one of the factors to attract capital.


  • Introduction
  • PRMS project sub-classification
  • Moving from contingent resources to reserves category
  • Aspects important in the demonstration of technical- and commercial maturity
  • Important definitions


At the end of this webinar, you will be able to:

  • Understand the “y-axis”, i.e. chance of commerciality of the PRMS resource matrix
  • Explain why it is important to assess the commercial maturity of an E&P project for oil companies
  • Understand under which conditions projects can move from the contingent resources category to the reserves category
  • Explain some of the commercial aspects of resource estimations, including tips and hints


Presently, many E&P companies are faced with challenges associated with the low oil price environment. It may be unclear which E&P projects now qualify for reserves, in view of reserves-based-lending (RBL) or attracting of venture capital. A reserves report or Competent Person’s report (CPR) is usually required. This webinar improves the insight into how reserves auditors assess, judge and value the available resources.

Target Audience

The webinar is particularly suited for the following oil and gas industry staff: petroleum engineers, reservoir engineers, production technologists, geoscientists, asset leads, discipline managers, petroleum economists, general managers, and commercial managers.
